jpa-patterns

JPA/Hibernate patterns for entity design, relationships, query optimization, transactions, and performance tuning in Spring Boot. Use for data modeling, repositories, and performance tuning in Spring Boot. Enable auditing: For cursor-like pagination, include id > :lastId in JPQL with ordering. Recommended properties: For PostgreSQL LOB handling, add: Remember : Keep entities lean, queries intentional, and transactions short. Prevent N+1 with fetch strategies and projections, and index for your read/write paths. - Covers entity mapping with auditing, soft deletes, indexing, and enumerated types; includes transaction management with read-only optimization and propagation strategies - Provides N+1 prevention techniques using lazy loading, JOIN FETCH queries, and DTO projections for lightweight reads - Demonstrates pagination with Pageable, custom repository methods, and cursor-based patterns for large datasets - Includes HikariCP connection pooling configuration, second-level caching guidance, and batch write optimization - Emphasizes testing with @DataJpaTest and Testcontainers, SQL debugging via Hibernate logging, and production-safe migrations with Flyway or Liquibase - Designing JPA entities and table mappings - Defining relationships (@OneToMany, @ManyToOne, @ManyToMany) - Optimizing queries (N+1 prevention, fetch strategies, projections) - Configuring transactions,...
